Resumen
The industries of cellulose and paper have generated large amounts of solid waste and effluents which have been used as soil conditioners and source of nutrients to improve physical and chemical attributes of areas growing forest species. This study analyzes the spatial and temporal variability of Eucalyptus urograndis regarding the chemical attributes of soil treated with cellulose residue. The fertilization of an experimental area in the Tres Lagoas county used a lime sludge/Oxyfertil (R) compound with a 2 ha. experimental grid containing 50 sampling points set up over it. Plant and soil samples were collected during three consecutive years (2014/2015, 2015/2016; 2016/2017). The assessment encompassed the following chemical attributes organic matter (OM); potential of hydrogen (pH); phosphorus (P), potassium (K+), calcium (Ca2+), magnesium (Mg2+) and aluminum (Al3+) contents; potential acidity H+ + Al3+, sum of the bases (SB), cation exchange capacity (CEC), base saturation (V%), and aluminum saturation (m%), at the 0.00-0.20 m layer. Classical statistical analysis was performed using SAS software while geostatistical analysis used GS(+). Low P, K+, Ca2+, and Mg2+ contents were indicated along the assessment period. OM and Al were the attributes that presented spatial and temporal dependence for all evaluated years. Also, the measured levels are considered sufficient for eucalyptus to establish in sandy soils. We also verified the space-temporal variability since nutrient ranges changed during the assessed period.
